Issue/Introduction

This article provides information on diagnosing a specific SRM failure.

Symptoms:
  • VMware vSphere Replication tab displays the virtual machine status as:

    RPO violation for VMs - NFC code: 10 NFC Error: the parent of this virtual disk could not be opened. Can't open remote disk.

  • On the PR host site, you see these messages from hostd:

  • You successfully issue the command nc -z to the IP address of the VR server on port 31031 and 44046, but in host on PR - vmkernel log, messages indicate a failure to establish a connection to R :44046.
  • Replicated base disks are found in a different datastore than expected.
  • SDRS is enabled on the cluster for the datastore group.
  • SDRS is configured for VR and ABR.
  • Error messages may indicate an issue with network communication from Primary Site to DR site from VR server. However, this is not a network issue.


Environment

VMware vSphere Replication 5.1.x

Cause

This issue occurs because SDRS is not supported for VMware Replication or Array-Based Replication in SRM.

For more information, see:

Resolution

To prevent this issue from occurring in the future, avoid using SDRS in an SRM environment in the future.

Warning: To resolve this issue, contact VMware Technical Support to work with an SRM-skilled engineer. For information on filing a support request, see Filing a Support Request in Customer Connect (2006985).
